No Bake Cafeteria Peanut Butter Bars

I loved these as a kid, brings back such great memories. A great recipe that requires no baking and ends up tasting like what a Reese’s cup aspires to be – When I saw it posted on Face Book new I had to save it. Cook time is cooling time. I've had to guess at serving size as it depends on how you cut it, but they are rich.
